  • WPF - Listbox bound to collection acts as one item

    - by user553765
    Hi, I have a listbox with the ItemsControl binding the ItemsSource to a readonly collection of strings. The ItemTemplate then declares the DataTemplate as a checkbox where its content is that of the name of the particular item in the collection and IsChecked bound to a property to determine whether or not the item is selected (it's just a listbox of checkboxes) This works fine with one exception - MouseOver the ListBox and it acts as if the collection of Strings is a single item; the whole box acts as if selected. This wouldn't be as much of a problem were it not for this also affecting the scrollbars where they won't get enabled - presumably because it considers the one item as being visible on the screen even though it in actual facts is x+ with only x-y showing on the screen. How do I get the listbox to act as if each individual string is its own item. I assume it acts this way because I declared a datatemplate in order to get a listbox of checkboxes?? Any help would be much appreciated!

  • Adding events to ScatterViewItems when implicitly creating them

    - by James Hay
    Not sure there's too many surface developers on here but hey ho... If i have a scatterview which implicity creates the ScatterViewItem objects (see below), is it possible to retireve the contact events for each scatterViewItem? Also when i wrap tyhe image object in a ScatterViewItem explicitly the item no longer works. Could anyone advise as to why this is the case? <s:ScatterView ItemsSource="{StaticResource DummyData}" > <s:ScatterView.ItemTemplate> <DataTemplate> <Image Source="{Binding Path=ImagePath}" /> </DataTemplate> </s:ScatterView.ItemTemplate> </s:ScatterView>

  • GWT Internet Explorer Problem

    - by bhargava
    Hi All, I am running into a problem which is quite a bit surprising.I have an GWT application,which i can run perfectly fine on Firefox,but the same GWT application does not open up in Internet Explorer. When using Firefox i use <set-property name="user.agent" value="gecko1_8"/> and when i want to run in Internet Explorer i change it to <set-property name="user.agent" value="ie8"/> and debug.This way i am sure that the problem i am having is not related to deferred binding. When using the Internet Explorer (IE 8) i cannot even get into the onModuleLoad() part of my application.It looks as if Internet Explorer has downloaded all its stuff ,but has nothing to display. Is there something that i am missing here Thanks Bhargava

  • JSF actionListener is called multiple times from within HtmlTable

    - by Rose
    I have a mix of columns in my htmltable: 1 column is an actionlistener, 2 columns are actions and other columns are simple output. <h:dataTable styleClass="table" id="orderTable" value="#{table.dataModel}" var="anOrder" binding="#{table.dataTable}" rows="#{table.rows}" <an:listenerColumn backingBean="${orderEntry}" entity="${anOrder}" actionListener="closeOrder"/ <an:column label="#{msg.hdr_orderStatus}" entity="#{anOrder}" propertyName="orderStatus" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="editOrder" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="viewOrder"/ .... I'm using custom tags, but it's the same behavior if I use the default column tags. I've noticed a very strange effect: when clicking the actionlistenercolumn, the actionevent is handled 3 times. If I remove the 2 action columns then the actionevent is handled only once. The managed bean has sessionscope, bean method: public void closeOrder(ActionEvent event) { OrdersDto order; if ((order = orderRow()) == null) { return; } System.out.println("closeOrder() 1 "); orderManager.closeOrder(); System.out.println("closeOrder() 2 "); } the console prints the'debug' text 3 times.

  • keypress event not being triggered only at start and end of text field in Firefox (JQuery)

    - by rlivsey
    I'm listening for keypress events on an input field with delegation. For some reason, Firefox doesn't trigger the delegated event for cursor UP when at the start of the field, or cursor DOWN when at the end. LEFT and RIGHT work as expected all the time. Directly binding an event listener to the field works fine, so it has to be something to do with delegation. Does anyone know if this is a know issue, I couldn't find anything on Google/forums etc..? $("div").delegate(":input", "keypress", function(e){ // doesn't get triggered }); $("div :input").bind("keypress", function(e){ // gets triggered fine }); Here's a demo which shows the issue - http://livsey.org/jquery.delegation.html

  • Is It Possible To Spring Autowire the same Instance of a protoype scoped class in two places

    - by Mark
    Hi ** changed the example to better express the situation i am using spring 2.5 and have the following situation @Component @Scope("prototype") Class Foo { } class A { @Autowired Foo fooA; } class B { @Autowired Foo fooB; } class C { @Autowired Foo fooC; } i am trying to understand if there is some way to use @Autowired and bind the same instance of FOO onto fooA and fooB while binding a different instance to fooC i understand that if the scope of FOO will be singleton it will work but i am wandering if there is a way to achieve the same goal while using a protoype scope. also please explain is this the correct usage of the autowiring concept ? am i trying to abuse the spring framework purpose

  • How do you set the height of an object to Auto when Animating in WPF?

    - by discwiz
    Tring to animate the expanding and contracting of a WPF Expander in .Net 4.0 using PowerEase. The animation works except I have to hardcode the height or bind to the height of an object in the expander which does not give the desired height. I need to set the "To" of the expander to Auto in animation. <Storyboard x:Name="myStoryboardContract" x:Key="myStoryboardContract"> <DoubleAnimation From="{Binding ElementName=MapsExpander, Path=ActualHeight}" To="30" Duration="00:00:3" Storyboard.TargetName="MapsExpander" Storyboard.TargetProperty="Height"> <DoubleAnimation.EasingFunction> <PowerEase Power="20" EasingMode="EaseOut"/> </DoubleAnimation.EasingFunction> </DoubleAnimation> </Storyboard> </Expander.Resources> <TextBlock x:Name="Text1" Text="Hi this is nothing but junk."/> </Expander>

  • How Do I See The Final Text Of A Query Resulting From A Call To mysqli->prepare?

    - by Joshua
    After code like this: $stmt = $mysqli->prepare("SELECT District FROM City WHERE Name=?")) { $stmt->bind_param("s", $city); $stmt->execute(); $stmt->bind_result($district); $stmt->fetch(); printf("%s is in district %s\n", $city, $district); How Do I See The Actual SQL Statement That Was Executed? (It Should Look Something Like "SELECT District FROM City WHERE Name='Simi Valley';") I already realize that in this simplistic case it would be very easy to simply reconstruct the query... but how can I access it in a general way that will work for very complicated prepared statements, and cases where I don't necessarily already understand the intended structure of the query, etc. Isn't there some function or method that can be called on the statement object that will return the actual text of the SQL query, after binding?

  • "Circuit breaker" for net.msmq?

    - by Alex
    Hi, The Circuit Breaker pattern, from the book Release It!, protects a service from requests while it is failing (or recovering). The net.msmq binding used with transactions give us nice retry and poison message capabilities. But I am missing the implementation of such a "Circuit breaker" pattern. A service is put under even heavier load by retries while it is already in a failure condition (like DB connectivity issues causing loads of blocked threads etc.). Anyone knows about a behavior extension or similar that explicitly closes the service host when defined failure thresholds have been exceeded? Cheers, Alex

  • How do I use global resources in WPF?

    - by Banford
    I have a WPF application which I would like to use some static resources in. I have created a Resource Library XAML file which contains a resource. I have also added a string into the Resources of the project through the Properties panel. I assumed I could just use these resources with the binding expression: {StaticResource ResourceName} But visual studio is telling me the resources are not found. Do I have to include some form of reference in my XAML? The examples I have seen only include resources locally such as: <Window.Resources>, <Page.Resources> etc I don't want to include the resources locally because I want them to be available to multiple parts of the application.

  • SmartGWT Server File Browser

    - by jluzwick
    Hi All: I have been looking for a SmartGWT example that would show me how to build a File Browser widget that takes the files from the local server's root directory. The user would be shown the files through the browser which they could then select to perform some processing operations. So far I have thought of using SmartGWT's Tree-Data Binding-Load from Local Data Widget and then grabbing a list of the directories using: new File("\").listFiles(); My Question is: Is there a better way to do this? Has someone already thought of this and has an example of their code that I can see? PS: I'm fairly new to GWT and Web Services but fairly competent with Java. If you believe there is a better way to do this (while still doing this through the web and not using Applets, please tell me). Thanks

  • Why would a TableAdapter populate a DataSet with "1/1/2000" for an entire timestamp column?

    - by Rob
    I have a TableAdapter filling a DataSet, and for some reason every select query populates my timestamp column with the value 1/1/2000 for every selected row. I first verified that original values are intact on the DB side; for the most part, they are, although it seems a few rows lost their original timestamp because of update queries performed programmatically before the issue was discovered. The DataColumn type is DateType, while the database (Postgres) column type is timestamp. Up until recently, this was all playing very nicely. I noticed the issue in a bound DataGridView control, and verified that this is not related to data binding by utilizing the 'Preview Data' option in the VS DataSet Editor. Usually when I notice unexpected values popping up in my application it's related to a mis-configured property, type conflict, or another silly mistake I've made. So after checking properties and types, and even recreating the TableAdapter from scratch, to say I'm a little baffled is an understatement. Does anyone have any ideas of what I could do to fix the issue and/or diagnose the cause?

  • jQuery click event still firing on filtered element

    - by Phil.Wheeler
    I'm trying to filter button events based on whether they have a CSS class assigned to them or not. Assume I have a button like this: <button id="save-button" class="ui-state-default ui-corner-all">Save</button> I want to get jQuery to select all buttons that currently do not have a class of "ui-state-disabled". The selector I'm using looks like this: $('#save-button:not(.ui-state-disabled)').click(function() { ... }); When the button is clicked, I'll call a different function, do some stuff and then add the class 'ui-state-disabled' to the button. However the button still continues to accept click events. I'm guessing this is because of two possible causes: The event binder looks only at the initial state when binding the click event and doesn't recognise that a new class has been added later on My filter ['... :not(.ui-state-disabled)] is not correct Any observations?

  • What does setting the GL color before doing a texture mapping operation do?

    - by quixoto
    I am looking at some sample code in a book that creates a jittered antialiasing effect by repeatedly rendering a scene (at different offsets) onto a offscreen texture, then using that texture to repeatedly draw a quad in the main view with some blend stuff set up. To accumulate the color "correctly", the code is setting the color like so: glColor4f(f, f, f, 1); where f is 1.0/number_of_samples, and then binding the offscreen texture and rendering it. Since textures come with their own color and alpha data, what is the effect (mathematically and intuitively) that setting the overall "color" in advance achieves? Thanks.

  • EventSetter - error XAML in Visual Studio designer

    - by pileggi
    Hi! I've done my TreeView all with XAML but now I'd like to manage an event with code-behind. The HierarchicalDataTemplate contains an Image. I need to capture the events MouseEnter / MouseLeave on the Image. I've tried in this way: <Image x:Name="imgArticolo" Source="{Binding imgArt}"> <Image.Style> <Style TargetType="{x:Type Image}"> <EventSetter Event="MouseEnter" Handler="iArt_MouseEnter"/> </Style> </Image.Style> </Image> But in the designer of Visual Studio appear the error: "Impossible to load a file XAML with EventSetter". How can I remedy? Thank you! Pileggi

  • .NET Recaptcha https

    - by TygerKrash
    We've started using the ASP.NET recaptcha control and it works fine. but one of the requirements we have is that all outbound traffic goes over Https. I know that recaptcha supports https, but It's not clear how to configure (or even if it is configurable) when using the ASP.NET plugin option. has anyone got any experience of this? I'll expand a little on what I've found so far.... The Recaptcha package contains 3 public classes RecaptchaControl, RecaptchaValidator and RecaptchaResponse RecaptchaControl is an Asp.NET control, the recaptcha specific methods on there seem to be concerning themes/look and feel. An instance of the Validator has a RemoteIP field (which I presume would represent the verification server), but I can't a way of binding that to the control. RecaptchaResponse seems to more or less represent an enum with possible responses (valid/invalid/failed to connect).

  • Save VM properties with EF code first

    - by Julien
    I thought this would be simple but can't find any good examples. public Class BookVm : ImplementsPropertyChanged { public int BookId {get;set;} private bool _favorite; public bool Favorite { get { return _favorite; } set { _favorite = value; OnPropertyChanged("Favorite"); MyDbContext.SaveChanges() // this does not work } } Then in my XAML bound to Book <CheckBox Content="Favorite" IsChecked="{Binding Favorite}" /> How and when do I call SaveChanges() on my DatabaseContext? I don't want to implement a save button. If I intercept the PropertyChange event and call SaveChanges, nothing seems to happen. My object is modified in memory but the database does not see a change. My BookVm class is created on application startup like so: foreach (var book in MyDbContext.Books) Books.Add(book); Where Books is an ObservableCollection<Book> in my MainWindowVm

  • Android Service Multiple Thread Design

    - by Gernot
    Hello, A new question about android and services. Currently I'm developing a App that should send images to a server. It should also be possible to send more images parallel. I made a service that creates for every image a new image. The activity can bind to that service and gather information about the progress. I want to show the current status for every image in a notification (and when the user clicks a notification, an activity with the progress for that image should be shown). But I get several problems with that approach. There are errors with binding, the notification pending event starts the activity completly new, so I lose information about currently sending images and so on. Can someone plase tell me, how I could design such a problem in a appropriate way. thx

  • Databinding in windows forms on an object graph with possible null properties?

    - by Fredrik
    If I have an object graph like this: class Company { public Address MainAddress {...} } class Address { public string City { ... } } Company c = new Company(); c.MainAddress = new Address(); c.MainAddress.City = "Stockholm"; and databind to a control using: textBox1.DataBinding.Add( "Text", c, "MainAddress.City" ); Everything is fine, but If I bind to: Company c2 = new Company(); c2 using the same syntax it crashes since the MainAddress property is null. I wonder if there is a custom Binding class that can set up listeners for all the possible paths here and bind to the actual object dynamically when/if I sometime later in the application set the MainAddress property.

  • use callback function to report stack backtrace

    - by user353394

  • Implementing DRY Forms

    - by virtualeyes
    Getting into Play 2.0, overall, blown away, great stuff. Anyway, wondering how one can achieve DRY forms in Play? If you look at the create & edit examples in the Computer Database Sample, you'll see that the form elements are repeated. With just 4 fields (in the sample form), no big deal, but when you're dealing with large, complex forms and/or handling many CRUD models, the duplication becomes a bigger maintenance issue. On the binding end ( form.bindFromRequest and form.fill(Foo) ), the implementation is so elegant for create/edit operations; is there a corresponding solution in the template layer?

    Hi I need to create an Orchestration in BizTalk 2006r1 that will consume a WCF basicHTTP web service. Does anyone have a pointers on how to do this please? The WCF service has been created by another team but I am able to request that they create an additional endpoint with binding configuration set to make calling from BizTalk SOAP adapter possible. I just created a simple test basicHTTP service that runs fine when tested from a command line client. When I got to BizTalk add web reference I am able to browse to the service but then get a message "Failed to add web reference" and it bombs out! Any help gratefully received. Thanks Rob.
